David Park
Plumber
Tankless water heater specialist serving Allen and north Collin County. 8 years experience, factory trained on Rinnai, Navien, and Noritz units. The big builders in Allen put in cheap 40-gallon tanks — I help homeowners upgrade to tankless and actually enjoy their master bath. Also do general residential plumbing.

Reviews
Tankless conversion - Twin Creeks (Plumbing)
David replaced our two old tanks with a single tankless unit and it is amazing. Our family of 6 can all shower back to back with zero wait. He sized the gas line properly which another plumber skipped. Very knowledgeable.
Response
Thank you Mike and Karen! Gas line sizing is critical for tankless — I have seen too many installs fail because of undersized gas lines. Glad your family is enjoying endless hot water.
Navien NPE-240A install - Star Creek (Plumbing)
Our builder put in the cheapest water heater possible. David installed a Navien and the difference is incredible. He explained the energy savings and the unit paid for itself in the first year.
Tankless flush and maintenance - 6 units (Plumbing)
David does annual maintenance on all our tankless units. Reliable, on time, and fair pricing. The units are running better than when they were new.
Response
Thanks Greenfield! Regular maintenance keeps those units running efficiently. See you next year.
